It looks like normal crayon, but it is specially made for draw on cotton clothes.
I take out one of my favorite cotton t-shirts, and start thinking what to draw ~
I added the coconut tress, a hot sun.... and a baby elephant! :)
This is not done yet.
I need to press on iron on it to make my color stay on the T-shirt permanently.
Place A4 paper on top the the drawing, and iron!
Now it is finished!
